PRESSURE DROP (∆p) INFORMATION FOR FILTER SIZING
HOUSING PRESSURE DROP
FDD040 XD630- 1000
The total Delta P through a filter assembly is given from Housing ∆p + Element ∆p.
N.B. All the reported data have been obtained at our laboratory, according to specification ISO3968 with
mineral oil having 32 cSt viscosity and density 0,875 Kg/dm3.
The housing ∆p is given by the curve of the considered model and port, in correspondence of the flow rate value.
ELEMENT PRESSURE DROP (filter elements 20 bar collapse)
The element ∆p (bar) is given by the flow rate (l/min) multiplied by the factor in the table here below corresponding to the selected media and divided by 1000.
If the oil has a viscosity Vx different than 32 cSt a corrective factor Vx/32 must be applied.
Example: 400 l/min with XD1000G10A and oil viscosity 46 cSt > 400 x 1,00/1000 x 46/32 = 0,58 bar
EXAMPLE OF TOTAL ∆p CALCULATION
FDD040XD1000G10ABB5BWFG2 with 400 l/min and oil 46 cSt:
Housing ∆p 0,15 bar + element Dp 0,58 bar (400 x 1,00/1000 x 46/32) = total assembly ∆p 0,73 bar

ELEMENT PRESSURE DROP (filter elements 210 bar collapse)
The element ∆p (bar) is given by the flow rate (l/min) multiplied by the factor in the table here below
corresponding to the selected media and divided by 1000.
If the oil has a viscosity Vx different than 32 cSt a corrective factor Vx/32 must be applied.
Example: 400 l/min with XD1000G10B and oil viscosity 46 cSt > 400 x 1,20/1000 x 46/32 = 0,69 bar

USER TIPS
The filter element that can be replaced is in the side opposite to the switch-over handle (a label on the handle show it).
When the indicator shows and the filter element must be replaced, the flow must be diverted to the clean element acting
with the switch-over handle (after having equalized the pressure though the manual valve, as described in detail in the
user handbook).
Follow carefully the instructions given in the User Handbook.
N.B. in case of cold start the indicator could give a false alarm: wait for the operating temperature to be reached and
press down the red pop-up button. If at this stage the red button pops up again and the electrical signal does not switch
off the filter element must be replaced.
The electrical indicator is supplied with normally closed contacts. The switching function may be changed to normally
open contacts by turning the electric upper part by 180°.
